Okay I grow all my orchids in a window sill, due to the fact that I am a broke college kid. I currently fill up saucers of hydroton, each day before I head out. This is how I am currently keeping some humidity for them.
Due to the heat and the shade on my porch I have them outside on a table hanging out.
But when winter hits they all have to go back inside to my grandmothers home where she has a large back room that we partially heat. We use propane, it sucks the humidity right out.
The room has a large set of sliding glass doors that face the west where they will get bright partially filtered light, there is a slight overhang over the doors.
How many humidifiers would I need to keep them at proper temp levels?
PS sooooo happy to have found this forum....FINALLY....because I feel windowsill growers definitely have some special issues....
Oh and I live in West Central Texas if that helps anybody, when it decides to get Cold it gets COLD and DRY...ugh
